我一直在寻找2天的时间来找到这个问题的解决方案，但还没有解决它。

网址：（/ HelloSpring / WEB-INF / hello.jsp） 编辑为（/HelloSpring/hello.jsp）

Folder structure 

import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

@Controller
@RequestMapping("/hello")
public class HelloController{

 @RequestMapping(method = RequestMethod.GET)
   public String printHello(ModelMap model) {
      model.addAttribute("message", "Hello Spring MVC Framework!");

      return "hello";
   }
}

hellospring-servlet.xml中

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context"

当我在tomcat上部署并运行它时，我收到以下错误 HTTP状态404 - 请求的资源（）不可用。

请你帮我解决这个问题。 任何帮助，将不胜感激。

答案 0 :(得分：1)

在web.xml中，您不应该使用<url-pattern>*.jsp</url-pattern>，因为您的控制器会“回复”/hello（与*.jsp不匹配）：

   <servlet-mapping>
      <servlet-name>hellospring</servlet-name>
      <url-pattern>/</url-pattern>
   </servlet-mapping>

在hellospring-servlet.xml中，您需要一种方法让Spring知道您希望以某种方式处理RequestMapping。 component-scan对@RequestMapping没有任何作用。您需要添加mvc:annotation-driven：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="
   http://www.springframework.org/schema/beans     
   http://www.springframework.org/schema/beans/spring-beans.xsd
   http://www.springframework.org/schema/context 
   http://www.springframework.org/schema/context/spring-context.xsd
   http://www.springframework.org/schema/mvc 
   http://www.springframework.org/schema/mvc/spring-mvc.xsd">

    <mvc:annotation-driven />

    <context:component-scan base-package="com.smithak.hellospring" />

    <bean id="viewResolver"
        class="org.springframework.web.servlet.view.UrlBasedViewResolver">
        <property name="viewClass"
            value="org.springframework.web.servlet.view.JstlView" />
        <property name="prefix" value="/WEB-INF/" />
        <property name="suffix" value=".jsp" />
    </bean>
</beans>

此外，您需要javax.servlet.jsp.jstl-api-1.2.1.jar下的spring-aop-4.0.6.RELEASE.jar，spring-expression-4.0.6.RELEASE.jar和/WEB-INF/lib个广告。

最后，您将转到/HelloSpring/hello网址而不是.jsp版本访问您的应用（由于我上面提到的原因）。
